It looks as if Google could be getting ready to do some more testing that involves new features for responsive ads in AdWords.
Spotted by Jonah Pession at HeBS Digital, Google is requiring two image sizes in some accounts. Not only is Google asking for the landscape look (1.91:1), they’re also asking for a square (1:) image.
Right now, the requirement is only active in some accounts. Pession was told by an AdWords rep that Google is going to be introducing new features for responsive ads and the image options will accommodate different ad placements.
There was a Google spokesperson who told Search Engine Land that, “We’re always testing new formats to see what works best, there’s nothing specific or any changes to announce.”
Google rolled out responsive ads in July. The ads are being served across the Google Display Network, and includes in native ad inventory. Advertisers will supply a short and long version of a headline, a description and image(s). The ads are then dynamically generated. The addition of a square image would gie response ads even more flexibility on mobile.
